* August 25, 2006 - initial release
|
|
* August 30, 2006
|
|
• Fixed a bug where cursor rects would be enabled even if the
|
|
textfield wasn't visible. i.e. it's in a scrollview, but the
|
|
textfield isn't scrolled to where it's visible.
|
|
• Fixed an issue where mouseUp wouldn't be called and so clicking
|
|
on the URL would have no effect when the textfield is a subview
|
|
of a splitview (and maybe some other certain views). I did this
|
|
by NOT calling super in -mouseDown:. Since the textfield is
|
|
non-editable and non-selectable, I don't believe this will cause
|
|
any problems.
|
|
• Fixed the fact that it was using the textfield's bounds rather than
|
|
the cell's bounds to calculate rects.

Contributed by Jens Miltner:
|
|
• Fixed a problem with the text storage and the text field's
|
|
attributed string value having different lengths, causing
|
|
range exceptions.
|
|
• Added a delegate method allowing custom handling of URLs.
|
|
• Tracks initially clicked URL at -mouseDown: to avoid situations
|
|
where dragging would end up in a different URL at -mouseUp:, opening
|
|
that URL. This includes situations where the user clicks on an empty
|
|
area of the text field, drags the mouse, and ends up on top of a
|
|
link, which would then erroneously open that link.
|
|
• Fixed to allow string links to work as well as URL links.
|
|
Changes by Darkshadow:
|
|
• Overrode -initWithCoder:, -initWithFrame:, and -awakeFromNib to
|
|
explicitly set the text field to be non-editable and
|
|
non-selectable. Now you don't need to remember to set this up,
|
|
and the class will work correctly regardless.
|
|
• Added in the ability for the user to copy URLs to the clipboard.
|
|
Note that this is off by default.
|
|
• Some code clean up.
